文摘：The crankshaft speed in a reciprocating hybrid power machine with regenerative heat transfer operating in pump mode and in compressor mode is considered. By analysis of the injection and suction processes, assuming that the maximum pressure losses in these processes are equal, a formula is derived for the crankshaft speed in pump mode with known crankshaft speed in compressor mode. In addition, the crankshaft speed in pump mode with known crankshaft speed in compressor mode is determined on the assumption that the pressure losses in injection and suction for compressor and pump modes are equal. By numerical analysis with water and air as the working media, the crankshaft speed in pump mode is expressed as a function of the crankshaft speed in compressor mode and the injection pressure. If the crankshaft speed in compressor mode is 2000–3000 rpm, the crankshaft speed in pump mode is found to be 100–150 rpm.
